What about passive bi-amping? Depending on what kind of speakers the person has, he may not have a direct connection to the drivers themselves. In my Paradigm studio 100's, the connection to the speakers is split before the crossover. In this configuration, when bi-amping even though the amplifier is sending the same signal to both inputs of the speaker, the internal crossover of the speaker is used such that the woofer is not drawing any current from the low frequency amplifier at frequencies above the crossover point (and vice versa for the Midrange and Tweeters). This eliminates the need for external crossovers, Which might cause problems anyways as you would have to consider the effect of adding additional filters to the existing circuit. Using the internal speaker crossovers means you don't have to fiddle with the crossover points, or worry about the slope of the filter, instead using the crossover the speaker manufacturer designed (using much more sophisticated equipment and design techniques than is available to the average home theater buff).

I have tried bi-amping my speakers, but the improvement in sound does not justify the cost of another Bryston at this time. I'll just settle for be-wiring my system for now (instead upgrading my DC-1 from base to V3 DD :)
If they ever had a blow-out on brystons, however, I would jump at the chance not only for the sound improvement, but also the visual effect a huge stack of amplifiers provides! :)

Regards,
Shane
